The correct answer is B.
OBJ-4.1: The netstat command is used to display active TCP connections, ports on which the computer is listening, Ethernet statistics, the IP routing table, IPv4 statistics (for the IP, ICMP, TCP, and UDP protocols), and IPv6 statistics (for the IPv6, ICMPv6, TCP over IPv6, and UDP over IPv6 protocols) on a Windows machine. This is a useful command when determining if any malware has been installed on the system and maybe maintaining a remote connection with a command and control server. The ipconfig tool displays all current TCP/IP network configuration values on a given system. The ping command is used to test a host’s reachability on an Internet Protocol network. The net use command is used to connect to, remove, and configure connections to shared resources such as mapped drives and network printers.
